摘要
利用超声多普勒流速仪 (ADV)对反向流动中圆射流流动特性进行了试验 .获得了该射流的横断面流速分布、射流扩展宽度和轴线流速沿程变化 ,以及横断面紊动强度、流速分布的偏差系数等紊动特性 .
The flowing characteristics of a round turbulent jet in counter flowing ambientce are studied by using Acoustic Doppler Velocimeter (ADV) measurement techniques. Several mean characteristics such as the distribution of velocity in a section,jet width,decay of centerline velocity,and turbulence characteristics including turbulence intensity and skewness of velocity distribution are obtained.
